ClassNotFoundException: org.springframework.scheduling.quartz.CronTriggerBean

spring4.3.6与quartz 2.2.3集成出现以下问题

实际上是因为quartz的配置信息用的是旧版本、而依赖的确是高版本的jar包

在quartz 1.8.6及以前版本的时候 调度触发器 依赖的类是 org.springframework.scheduling.quartz.CronTriggerBean

在2.xx版本之后就改为了org.springframework.scheduling.quartz.CronTriggerFactoryBean

因此当你依赖2.x.x版本之后只需将调度触发器的依赖类改为 org.springframework.scheduling.quartz.CronTriggerFactoryBean即可

在这贴出我spring-quartz.xml的配置文件,供大家参考:
